There are a couple of details that changed in the anime, but I understand why they did it. Regardless, it's really fun to see a bit more of the characters' personalities in here ~
the novel is also a bit different, it's a little repetitive so it's taking me a long time to keep up Σ(  ̄□ ̄||) I think I like how the anime is voiced over and is more colorful, but I like the manga the best (づ ̄ ³ ̄)づ
